College to Pro Rank questions

[Yoavoshimaru 0]

So I know that for a while now college grand champions get to come in a Makushita (15, tsukedashi, right?).  Presumably people who are good enough to be college grand champions will be decent (or better) pros.

My questions are about those collegiate wrestlers who aren't champions, but still want to go pro:

- How often is this?

- Do they come in as mae-zumo?

- Is it solely their decision whether to go pro or not, or does their coach / university have to approve?

- What's the highest rank achieved by a non college champion who became pro, and who achieved it?

Thanks for any information  :-P
